There is no doubt that the SM57/58 mics are low output mics.
It is also unfornunately the case that the Fast track series do not have much in the way of mic amp gain, but it should work!
The FT usb sports an LED that indicates a level of -40dBu, does this ever blink? I do not have that AI to hand but I do have a FTT pro and this is how that goes..
SM57, gain max, mic at 100mm from gob,"Mary had..." just lights the LED and thus gives me about -25dBFS in my DAW software.
Be systematic in your tests and tell us the results.
